This invention relates to means for removing excess material in the production of pottery ware, Vand ythe principal objecttof the same is to provide for the automatic removal of the excess plastic material or clay which accumulates asa result of the profiling or shaping operation. l

The means employed in general consists in a conduit member which is mounted 'incooperative relation with the profile and' has `an inlet port so disposed that the excess matrial will be forced therinto by the pressure set up between the profile and mold, the

'latter preferably being of the rotative ty`pe and the proiile stationarily mounted with respect to the mold, means being provided for conveying the excess materialfrom the conduit member.

With the foregoing and other objects and advantages in view, the invention vconsists in the preferred construction and arrangement of the several parts which will be more fully hereinafter described and claimed. In the drawings Fig. 1 isa vertical section i on the line 1-1 of Fig. 3, showing sundry parts in elevation.

Serial-No. 143,994; and 12 designates a mold, 0. supported by, saidvchuck under a profile13, whichis shown vin Fig. 3 as having thereon a. reinforcement 13a. The profile 13 is ad- ]ustably secured to a holder 14 by .means of bolts or screws 15; vertical slots 16 lin the profile 13 and horizontal slots 17 in the holder 14 which permit'v universalI adjust- Ament of the :profile 13 with relation to the holder 14 andthe chargeof material 18 on the mold 12. l

Theproile 13 is shown in Figs. 1 and 3 as having connected thereto a bracket 19 by means of screws 20.

Vertical slots 21 in the bracket 19 and horizontal slots 22 in profile 13 permit universal adjustment of bracket 19 with relation to the profile 13 and to the charge of material 18 Von mold'12.

^ The bracket 19 terminates at the lower end thereof in -a `conduit member 23, which is shown in Fig. 3 as made in onev with bracket 19, forenclosing part of the periphery of the inner half of a spiral or helical screw or cony veyor 24, leaving at the underside thereof an` g5 opening 38, lengthwise said half, and enclos# ing the entire iperiphery'of the greater part of the outer -half. of screw 24.,1 leaving an opening 39`at the outer end of the conduit member 2 3 at'the underside thereof, as shown in Fig, 1. Y J

The scr-ew 24 isl shown-'asheld' in a plane, which -is substantially parallel to the profile 13, over material 18 by vmeans of a' shaft-25, l

' and 29 respectively of conduit member 23.

A cylindrical groove Slin the forwardside I of the' profile 13 serves to enclose thevrear i p art of the screw 24 at theinn'er vend thereof,. 13g.

whereby the lower or acting part of said screw is brought nearer the profile 13.

The screw 24 is shown as left handed in Fig. 1, and its direction of rotation is indicated by an arrow in F ig. 3 as counterclockwise.

A right hand screw may be employed and rotated in a clockwise direction, if desired; in

the latter 'case the conduit 23 may be dis-V pensed with and the screw 24 operated as a propeller, to remove the surplus material on the mold 12 and on the' disc '61, which is hereinafter described, as soon as it reaches the screw 24; in the modification shown in Fig. 1 the action of the inner end of the screw 24 under the inner end of the conduit member 23, which is shown as open at the underside thereof, will tend' to transfer and p1le up the surplus material from the mold 12 into the inner end of said conduitmember until it will fill up the inside of the conduit member, which, with the groove 81 in profile 13 encloses or nearly encloses the inner 'end of the screw 24, whereupon said material will be forced into the outer end of conduit 23, which l completely encircles the screw 24, and conscribed.

i mitted by contact and dribbling to the maveyed by the outer end of screw 24 to a trouO'h 40 and channel 42 which are hereinafter e- A sponge 30 is shown as kept in contact with the upper surface of material 18 by means of a bracket 31, which is adjustably connected to an extension 19av of bracket 19 by means of screws 32; vertical slots 33 in bracket 31 and horizontal slots 34 in extension 19a permit universal adiustment of bracket 31 and thesponge 30, carried thereby, with relation to said material. The sponge 30 is normally kept moistor wet by means of a spraymf Huid, preferably water, which may be suitably treated, from. a nozzle 35 of a sprinkler 36. The intensity of said spray may be regulated by means of a valve 37 o n 'saidsprinklen The moisture from the sponge 30 is transterial 18 on mold 12, to soften the material,

for facilitating the actionofthe profile 13,

thereon; Aalso to cause said material more readily to flow on the forward4 side of said profile 13 and to have lthe surplus thereof taken up by the screw 24, to be continually transferred thereby in a direction preferably from the apex of the mold 12 to the periphery thereof.

The opening 38 in the underside of the inner end of conduit-23 permits the excess of the material to pass intothe zone of action of screw 24 in the conduit 23, to be propelled therethrough by said screw conveyor to` a point near. the outer end of the conduit 23,

where the opening 39 permits the excess of' material to be discharged therethrough into a substantially lcircular trough 40, whichA is shown as concentrically placed with relation to the mold 12. It will be seen that the rotation of the mold forces the excess material into the opening 38 as it accumulates against the shaping edge portion of the profile, said portion preferably being shaped to form in conjunction with the mold a converging space into which the clay is forced by the rotating' An annular space 83 is shown betweenv trough 40 and chuck 11 with the mold 12 thereon, to provide room for molds' of lar er slzes than that of the mold 12, shown in 4ig.

1. The annular space 83 may be spanned by a deflector disc 61, as shown in Fig. 1. The

disc 61 may rest with the inner edge thereofon the mold 12, when the latter is in operative position .under the profile 13, or, in reclprocatmg jiggers, with the 'outer' edge thereof -on said trough, when the mold is withdrawn.l lengthwise the axis thereof, as gescrlbed 1n my above copending applica- 1on. f

When nonreciprocating jiggers are used, the dlsc 61 may be raised with the trough 40 each time when a mold is to be replaced in chuck 11; the trough 40 may then be adjustably connected to the profile 13 in the same way as the conduit 23; or inde endent means may be provided for raising said trough with the disc 61 thereon, when a mold is to be removed, and for lowering ,the same into positlon after anew mold has beeni placed into chuck 11; the disc 61.is then to be intercepted by the mold 12 and revolvedl therewith, whereby any surplusmaterial lon said disc may b'e thrown olf by centrifugal force and transferred into the'trough 40..

The trough 40 serves to receive part of the discharge from the' conduit 23 and also the particles of material, lwhich may be detached from the charge 18 and from the disc 61 and thrown off therefrom either by the screw 24, by centrifugal force, by the trimmer or otherwlse.

A spray of water from a nozzle 41 of a sprinkler 45 serves to liquefy or semiliquefy the materialin said trough 40, to cause it to fiow to the channel 42, which is shown in Fig.

i vided, if desired.

jA. tangentially disposedscrew conveyor 43 is placed in the channel 42,'continually to remove said liquefied or semiliquefied waste material from said channel, to deliver it to any required destination, such as storage bins, where the waste material maybe re.

, claimed in any suitable manner. The channel 42 may be 'ribbed'as at 42a in Fig. 1; the said conduit 23 may also be ribbed.

A sprinkler similar to 45- maybe em' ployed also for` directing a spray of water to the top' of the disc 61, to wash down therefrom any material, which may adhere thereto, into the trough 40, if desired.

The screw conveyor 43 is shown as right handed and single threaded, but it may also be left handed and multiple threaded, 4if desired.

The ldirection-of rotation of the screw conveyorf43 is indicated by an arrow in Flg. 1 as counterclockwise; when a .left handv screw conveyor 43 is employed, the direction of r0- tation may be clockwise instead. l

A 'valve 46 is provided on sprinkler 45, for regulating the intensity of the spray. fromthe nozzle 41 into the tro-ugh 40. l

A water main 47 is provided, to supply I water to the sprinklers 36 and 45, which are connected thereto by suitable fittings; said main has also connected thereto an additional sprinkler 48, which terminates in a nozzle 49, to direct a sprayof water directly to the charge of material 18 on the mold; a valve is provided on the sprinkler48 to regulate the intensity of the Spray delivered by the .nozzle 49. l v The water main 47 has thereon also a valve 51, which is controlled by a cam 52,-"whi'chis shown in Fig. 2 as mounted on a shaft or spindle- 53, supported on suitable. bearings 54,v

which may be mounted on the frame 44. The

' 'Valve 51 serves intermittently to admit water to the sprinklers 36, 45, and 48,.

' Athrottle valve 55 is also -provided on the main 47, for manually closing and opening said main and for regulating the volume o water passing therethrough.l

The conveyor shaft 25 is shown as having.

.4 revolvably mounted thereon at theouterend thereof a material crushing and conveyor cleaning gear 56, which is shown in Figs. l.

and 2, in mesh with the end of screw conveyorl 43, but the shaft25 is not driven by the gear` 56, which Ais loosely swivelled thereon 'and serves to disintegrate the material discharged by screw 24 and remove from the end of the conveyor 43 any particlesof plastic` vmaterial which may yadhere-thereto', thereby increasingthe efficiency of said conveyor.

vTo enable the material crushing and cleaning gear 56 to-be used for cleaning the entire length of the screw'conveyor 43, the `gear 56 may be disconnected: from the' shaft 25, or

a separate gear56 provided, andmounted on an independent spindle 56%, see Figs. 11 'and- 12, which maybe mounted in a4 slidmgframe 56-b and secured in position by' collars-56", the frame 561 having a dove-tail slidable mounting on the channel member 42. A crank gear o r analogous member 56d, rotatably mounted in a supporting bracket 56e shown secured to one side of the channel member 42, maybe used as an actuating means for the sliding frame 56", said. gear 56d4 being connected with -saidframe as by a` connecting rod 56t and pins 56g and 56h, a plurality of securing holes 56 being provided in the crank gear 561 to permit ladjustment of the throw of said gear.

The gear 56d is shown in mesh with a drive pinion 563, which may be drivenfrom any 'suitable source.- The sliding frame 56b mayA also` serve as a cover for the channel 42.

The shaft 25 may be driven'by any suitable means, not shown. For properly the material, which -ndsits way into the trough 40,I I providea number of modifica- .tions of crushing and kneading or mixing devices, which are illustrated in Figs. 5, 6, 7, 8 and 9 of the drawings. r 7

In the-modification shown in Fig. 5 spheri-- cal balls 5.7, which may be made of steel or any other suitable material` are placed`\ in the trough 40,' and are propelled by the screw cony vevor 43 in the direction of the arrow in Fig.

5';vthe number ofballs 57 may' be larger `than as shown in Fig. 5, and the weight as Well as the impact'of the balls 57 against the louter liquefying or semiliquefying vwall of said trough, which impact isy dueto vcauses the coils of said spring or springs 58 both to rotate each around-its axes and to slide w1th relatlon to the trough 40, thereby1 scraping oii" the particles of material, which.

may be adhering to the walls inside of said trough, and also crushingjand'kneading,or mixing the same with the water in the trough.

The spring or springs 58 are kept by the.

trough cover .from being thrown loutof the trough by the conveyor 43.

Inathe modification shown in Fig. 7 rollers .59 are employed in place ofthe 'balls shown in Fig. 5; an enlarged view of-'the rollers; 59

is shown in Fig. 10. and their action is` simi' ilar to that of the balls 57, exceptfthat the "rollers 59 have a larger surface in' contact with the inside'of the trough 40, which mav be pronearly Hat shape, for said rollers to rollupon.

vided with a bottom, having-a suitable flat or In the modification shown in Fig. 8, I pro- .i

vide centrifugal vanes 60, which are extending into the troughv 40 lfr ron'i the-annular `or s to reciprocating jiggers, such :1s-described in my aforesaid copending application for patent, but .it may also be used with nonreciproeating jlggers. Y v

In reciprocating jiggers the disc 61 comes lo into contact with the mold 12, when the latter is moved into operative position, as described in my above copending application, and said mold 12 imparts a rotary motion to said disc, whereby thev vanes 60 are made to churn the 15 contents of the trough 40 at avery high velocity, thereby thoroughly mixing the water with the plastic material in the trough'to a liquid amalgam, especially if an abundance of water be allowed to iow into the said trough from the sprinklers 36, 45, and 48.

The trough 40 may be provided with internal projections or other irregularities to assist in thedisintegration of thematerial.

The vanes 60 are not in mesh with the screw I conveyor 43, which is shown in Fig. 8 as disposed outside the circle of action of said vanes; the screw conveyor serves only to rcmovethe contents of the channel 42 into which the fluid or semiiiui-d mass from the 3o trough 40 is discharged by gravity; the channel 42 is situated at a lower level than said trough,as in the modiiicationjshown in Fig. 1. To prevent spilling of the contents of .the

trough when churned by the vanes 60, I prefer 35\to have a modification 40a of the trough,

which is covered, as shown in Fig. 9, where an annular lid 62 is i shown as secured to the channel shaped trough 40a by means of bolts 'or screws 63.

40 y When a profusion of water is allowed to omitted; the trough 40a with'the lid 62 thereonshould then have a spiral outline of a centrifugal pump casing, and water from the main 47 shall only be admitted thereto by the valve 51 and cam 52 during the time when mold 12 is in operative position, when the disc 61 with the vanes 60 is in motion. y

The disc 61 is shown in Fig. 1 as vraised by the mold above the inner edge of the trough 40, with the vanos thereon extending into the -said trough. without their touching the 5 bottom or sides of the trough, to facilitate the revolution ot the disc 61 with the vanes 60 Y thereon at thehigh velocities, at which the .mold 12 is running,and to prevent the retardation of or undue frictional resistance to the motion of the mold.

l When the mold 12 is withdrawn lengthwise its axis of revolution, as described in my above copending application, the disc 61 or the vanes 60 or both, are vbrought byl the action of gravity into cont-act with the trough 40,

whereupon their rotary motionisy gradually arrested by friction on said trough, and they are shortly thereafter brought to a standstill,

thereby. l

In the modication shown in Fig. 4, where the lower end of a profile 7 9 is shown, I provide an angular conduit 66-67, which may be connected to the 'profile 79'in 'the same way as thecondu'it 23 in Figi"1, and4 which has thereon two branches: a nearly verticall branchy I66 and a substantially horizontal branch 67. A conveyor screw 68 is revolvably supported in position in the branch 66 by means of a shaft 69, which is journalled in the end walls 70 and 71 of the branch 66, and` may. have rotation Aimparted thereto by any suitable means. The action of screw 68 is similar to the action `of the screw 24.

' An opening 72. lin the s ide of the branch 66 permits the surplus material from a charge'65 1n -a mold 64 to enter the `branch under the influencent the profile 79, the upper part of which isf not shown in Fig. 4 of the drawsings. This action just mentioned takes place when the mold 64 is revolved-by'the chuck of the jigger, which is also omitted in'Fig. 4.

into the branch 67, where it is transferred in the direction from left to right in Fig. 4 by means ofv a conveyorvscrew 73, whichl is revolvably4 supported in position in the branch 67 by means of a shaft 74, whichqnay be sup ported at o-ne end thereof at a point, situated to the rightv ofconveyor 73, by suitable bear'- ings .85, which may be made. in one with the ends lof the branch 67, as shown in Fig. 4,

The material, which passes into the branch 66, is then raised by screw 68 and discharged or independently thereof, if desired. l

An opening 75 in the underside of the branch 67 serves to ldischarge the material from said branch intoany desired receptacle vor carrier, to be taken to any desired destination.

A gate 76 is provided .for the opening 75, whereby the discharge ofthe material therethrough may be regulated or shut off altogethe'r.

Another discharge opening 84-- may bel pro vided at the end of the conveyor casing 67, if desired. l The angular conduit I66-67 may be adjustably connected to the prole 79 by means of a suitable bracket 80 thereon, in the same wayas the .conduit 23 isconnected to the profile 13 in Fig. 1.

A suitable moistening device or sponge 77 isv shown in Fig. 4 as supported by a bracket 78, which maybe adjustably connected to bracket 80, and is employed for moistenin'g the charge ofmaterial. 65 in the mold 64 in 4. A Sprinkling devices similar to those shown in Fig. 1 may also be employed` in the modification of my means for removing excess ofmaterialin profiling, which' shown i Fig; 4:.

`lents and obvious modifications of the same Many other changes may be made inthe details-of my above removing means with-, out departing from the main scope of my invention, and parts of my inventionmay be 4used without other parts, y I do not therefore restrict myself to the details as shown in the drawingsg'but I intend to include also all mechanical equivawithin the scope'of my invention.
